Remove the "ilink" cross-references from within a few subsection header.

It didn't make sense for a subsection header to point to a different
chapter in a printed document. No hyperlink in print :)

Add a sentence at end each of these sub-sections to instead point
to that cross-reference. (The hyperlink is still in the section
but now can be read.)
